Abstract: Phase noise is a fundamental characteristic of an optical frequency comb (OFC). Low phase noise OFCs are powerful tools for the comparison of different optical clocks, precision spectroscopy, and time and frequency transfer. After a description of the phase noise, we summarize the noise sources affecting OFCs and the techniques for suppressing the noise, and pres-ent several low phase noise OFC systems developed in our lab. Finally, we review the prospects for future developments.
